LYSANDER BUTTON AND THEO. E. BUTTON, OF WATEBFORD, NEW YORK.

IMPROVEMENT IN STEAM-PUMPS.

Specification forming part of Letters Patent No. 119,314, dated September 26, 1871.

To all whom it may concern:

Be it known that We, LYsANDER BUTTON and THEO. E. BUTTON, of Waterford, in the county of Saratoga and State Of New York, have invented certain Improvements in Steam-Pumps, of which the following is a specification:

Our object is to so arrange the several parts composing the invention that the utmost economy of space and Weight of material, With such distribution of parts as Will insure a maximum t of strength and the. greatest efficiency of operation shall be attained.

Figure l is a side elevation off a steam-pump embodying our invention. Fig. 2 is a plan of the same. Fig. 3 is avertical section of the same.

A is the vpump-cylinder and B is the steamcylinder, in Which slide the closely-fitting pistons V W, directly connected by the piston-rod K. R is a cross-head secured to the piston-rod K, and connected, by the connecting-rods S S, to the crank-pins Y Y in the hubs of the balance-Wheels F F, which are keyed upon each end of the shaft -O revolving in the bearings N N.V T is an eccentric upon the shaft O, Which imparts to the lower end of the Walking-beam H a reciprocating inotion, Which is in turn imparted to the steam-valve Mthrough the valve-rod J. Iis the standard upon Which the Walkingbeam vibrates. The steam-cylinder head D and the pump-cylinder head E, t0- gether with the braces or frame C C, are cast in one piece, While the bearings N N and the standard I are cast in one piece with or securely bolted to the steam-cylinder head P. Both cylinders being bored out and faced up in a lathe, and the heads D and E being turned upon the centers of a lathe, the cylinders A and B must be exactly in line 7 When bolted tothese heads. The same is true of the bearings N N and the standard I upon the head P. It is obvious that the bearings N N may be upon the pump-cylinder head U if for any reason preferable.

We claim none of the parts composing our improved pump taken separately; but

What We do claim isl. The arrangement of the pump-cylinder A E U, the connectingirame or bars C G, the steamcylinder B D P, and the'bearings I N N, as.
